[Feature Request]: New platform scheduled pipeline to check external version updates

### Description

Implement a platform scheduled pipeline to check the latest version for all external sources, e.g., public external actions/steps or tools.
Discuss a possible MVP with the team, for example:

Check https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuring-dependabot-version-updates

OR
- List all versioned resources (declarative JSON, yaml or other)
- Compare for each current vs latest
- Provide a job summary of the findings, highlighting what's new
- A step further could be to automatically create an issue whenever a mismatch

### Versions to check
>Note: First draft not exhaustive

- PSRule action
- Bicep
- Az cli
- PS version
- PS modules (Az, powershell-yaml)
- GH Runner/ADO Agent OS
- Autoassign PR action
- ...
